  • Publication number: 20050217830
    Abstract: An oil cooling and filtering system of a transmission is described which comprises first and second oil passages formed in a given portion of a housing of the transmission. The given portion has an outer surface exposed to the outside of the housing. The first oil passage is fed with a compressed lubricating oil from an oil compressing means and the second oil passage is led to moving parts of the transmission which are to be lubricated. An oil cooler is connected to the outer surface of the given portion. The oil cooler includes a water flow passage and an oil flow passage which are isolated from each other. The oil flow passage has an inlet opening connected to the first oil passage and an outlet opening connected to the second oil passage. An oil filter is installed in at least one one of the first and second oil passages for filtering the lubricating oil flowing in the oil passage. With this arrangement, the oil cooler can be compact in size and simple in construction.

  • Patent number: 6134377
    Abstract: The regenerative apparatus for feeding back a disk type recording medium has a control means for putting the regenerative apparatus into the feedback halt state when, for example, a display command of a television broadcast program is outputted when the regenerative apparatus performs a feedback operation and selects signals from the regenerative apparatus, selecting video signals of the television broadcast program, canceling the feedback halt state of the regenerative apparatus and putting it into the feedback state when a display command of video signals from the regenerative apparatus is outputted thereafter, and selecting video signals from the regenerative apparatus.

  • Patent number: 5819192
    Abstract: There is disclosed a motor vehicle having a set of front wheels, a set of rear wheels, an engine, and a transmission driven by the engine and having a transmission output shaft. The motor vehicle further has a transfer including a variable torque trasmitting (VTT) clutch for varying a distribution of torque between the set of front wheels and the set of rear wheels depending upon degree of engagement thereof. A clutch activating pressure is generated and transmitted to the VTT clutch under the control of a mode selector valve.
